  3. 2. Spatial Marriage Problems and Epidemics

    Författare :Fabio Lopes; Maria Deijfen; Markus Heydenreich; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical Statistics; matematisk statistik;

    Sammanfattning : This thesis consists of four papers covering three different topics on the modeling of large real networks and phenomena thereon. In Papers I and II, we propose and study the properties of a bipartite version of the model introduced by Deijfen, Holroyd and Häggström for generating translation-invariant spatial random graphs with prescribed degree distribution.

  4. 3. Stochastic Epidemic Models : Different Aspects of Heterogeneity

    Författare :Mathias Lindholm; Tom Britton; Maria Deijfen; Gianpaolo Scalia Tomba; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; Matematisk statistik; matematisk statistik; Mathematical Statistics;

    Sammanfattning : This thesis is concerned with the study of stochastic epidemic models for infectious diseases in heterogeneous populations. All diseases treated are of SIR type, i.e. individuals are either Susceptible, Infectious or Recovered (and immune). LÄS MER

  5. 4. Random Graph and Growth Models

    Författare :Sebastian Rosengren; Maria Deijfen; Pieter Trapman; Tatyana Turova; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical Statistics; matematisk statistik;

    Sammanfattning : Random graphs is a well-studied field of probability theory, and have proven very useful in a range of applications — modeling social networks, epidemics, and structures on the Internet to name a few. However, most random graphs are static in the sense that the network structure does not change over time. LÄS MER

  7. 5. Random Graphs: Dynamic and Multi-type Extensions

    Författare :Sebastian Rosengren; Maria Deijfen; Olle Nerman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Random graphs is a well-studied field of probability theory, and have proven very useful in a range of applications. However, most random graphs are \textit{static} in the sense that the network structure does not change over time; they also tend to consist of \textit{single-type} objects. This puts restrictions on possible applications. LÄS MER
